Received October 30, 2008 Abstract — The residual protective effect of n-component mixtures of o-oxyazomethine derivatives at the corrosion of iron in 1 M H2SO4 decreases with time and an increase in temperature of the environment and increases with an increase in the polarity of substituent groups in the molecules and the inhibitor concentration in the solution. These regularities are interpreted based on the principle of the linear free-energy relation. DOI: 10.1134/S2070205110010181
